All, This patch converts the x86-64 arch to use the generic timeofdayinfrastructure. It applies on top of my timeofday-core patch. This is afull conversion, so most of this patch is subtractions removing theexisting arch specific time keeping code. This patch provides only theTSC and HPET clocksources for x86-64. To get full replacements for thecode being removed here (ACPI PM timer support, specifically), thefollowing timeofday-clocks-i386 patch will need to be applied.
